Readdle'sPrinterProUpdatedWithNewDesignAndNewDesktop-ClassFeatures

Apple's AirPrint not quite cutting it? Then you'd do well to check out Printer Pro by Readdle, which has just been updated with a new iOS 7-inspired design and, more importantly, new features.
With regard to the app's new design, I'll let Readdle do the describing:

Printer Pro 5 is flat. It’s flatter than your ceiling. All controls are there. It takes just a few taps to adjust your print settings and hit the “Print” button.
